The Pussycat Dolls were an American pop girl group and dance ensemble, founded in Los Angeles, California, by choreographer Robin Antin in 1995 as a burlesque troupe. After attracting media attention, Antin negotiated a record deal with Interscope Records in 2003 turning the group into a music franchise comprising Nicole Scherzinger, Carmit Bachar, Ashley Roberts, Jessica Sutta, Melody Thornton and Kimberly Wyatt. Overseen by Antin, Interscope and various partners, the group was transformed into a global image and commercial brand. The Pussycat Dolls were launched into mainstream recognition following the release of their best-selling debut album, PCD, which contained the number-one singles "Don't Cha", "Buttons", and "Stickwitu". However, despite their commercial success, the group was plagued by internal conflict due to the overemphasis on Scherzinger, the group's lead member, and the subordinate treatment of the other members. Bachar's departure from the group preceded the release of their sophomore and final studio album Doll Domination, which contains the worldwide hits "When I Grow Up", "I Hate This Part" and "Jai Ho! (You Are My Destiny)".

In 2009, they announced a minor hiatus and was later revealed to be an official break up. The Dolls brand diversified into merchandise, reality television programs, a Las Vegas act, product endorsements, spin-off recording groups (Girlicious, Paradiso Girls, G.R.L.) and other ventures. In 2009, Billboard ranked the Pussycat Dolls as the 80th most successful musical act of the 2000s. The group has sold 50 million records worldwide, making them one of the best-selling girl groups of all time.
